[์˜๋ฌธ] Ideal dental esthetic restoration agents require suitable properties of/physical chemistry, organic affinity, durability, and anticariogenic nature in order to recover esthetics, and masticating function. For this study, the composite of nonorganic and organic antibacterial filler (AP-7) with 0.5, 1, 2, 5wt% was added to the conventional fissure sealant (ConciseTM 3M Co., St. Paul., MN, U.S.A.) to produce a new antibacterial fissure sealant. The experimental groups are compared with conventional sealant of physical and biological properties of the polymerizing depth and time, the degree of water absorption, the solubility, the cytoxic effect and antibacterial ability. The result was as follows : 1. The polymerizing depth was decreased by the increasing of the amount of filler(AP-7) compared with the conventional sealants. It was also verified that the nature of fissure sealant was not reduced very much. There was significant differences between the experimental and control groups(p<0.05). 2. There was no significant difference in the polymerlizing time between the AP-7 fillers added experimental group and conventional Concise fissure sealants(p>0.05).two groups according to the AP-7 content (p>0.05). 3. The water absorption and solubility degree of the fissure sealant added AP-7 filler showed no significants difference with the control groups (p>0.05). 4. The antibacterial ability of the antibacterial fissure sealant which was produced by the addition of AP-7 fillers to the conventional sealants ConciseTM was increase by the increasing of amounts of fillers. The number of bacterial colony was obviously reduced with the comparison of the control group. In case of the fissure sealant produced by the addition of AP-7 with 5wt%, the colony barely grew up, and with the addition of antibacterial filler, excellent antibacterial ability could be produced without weakening the physical property of the basic fissure sealants. 5. The the reaction index appeared as 0/0 by the cytotoxic effects of the antibacterial filler(AP-7) and that of the fissure sealant itself showed 0 in the cellulous discoloration index and the lysis index. The measurement of the cytotoxic effect on the new product which was made by adding antibacterial filler to the fissure sealant revealed that the cellulous discoloration index and the lysis index measured 0. Thus the response index appeared as 0/0. as a result, it was proved that the fissure sealant containing antibacterial filler which was produced for this study has no cytotoxic effects. The physical property of the antibacterial fissure sealant containing AP-7 filler does not weaken traditional fissure sealant''s physical properties and has no cytotoxic effects. The antibacterial ability will increase with the increase of AP-7 content as well. Therefor, it was proved that the antibacterial fissure sealant made for this study had an excellent oral antibacterial ability. In conclusion, the system developed in the study enhances the mechanical property, and it can be used as a dental esthetic recovery material for composite resin and antibacterial fissure sealant which has inhibitory effect against bacterial attachment.ope
